Control pests with specific pesticides to prevent future plant death.
An excess of watering can cause the formation of fungi and the rot of the plant.
This plant can be propagated by cuttings, which is the easiest or by seed, which is a little more complicated.
The seeds are sown in pots wider than they are tall, with holes for drainage, filled with substrate.
Then, the seeds are watered and placed on the surface, taking care not to pile them up.

You can also add some homemade fertilizer, such as eggshell tea or banana shell tea.
The time of sowing or transplanting should be done in spring when the frosts have passed.
Follow these steps
1. Let the plant out of its current pot. This process will be easier if the pot is plastic.
Otherwise, tap the sides of the pot lightly to loosen the soil and roots from its walls.
I recommended that you use gloves to avoid getting pricked with the thorns.
2. Prepare the new pot; it is vital to have drain holes, if you don’t have them when you buy it, please make them carefully.
Cover the bottom with a bed of thick stones to help keep those holes free and improve drainage, and use substrate for the succulents to enrich it with a slow-release fertilizer.
3. Transplant the succulent, simply place it in its new container, with the green part a couple of centimeters below the edge of the pot, and add the necessary substrate.
If it’s a succulent plant shoot, try to untangle its roots as much as possible, or carefully separate it by gently prying it with a fork.
In the case of children, it is sometimes advisable to wait a few days after separating them from the mother plant to close their possible wounds.
It does not need pruning.
